Waterproof cable connector

Abstract

A waterproof cable connector has a body, two plugs and at least one sealing ring. The body has a chamber and two through holes communicating with the chamber. The plugs are respectively connected to the body via the through holes and each plug has a clamping ring and a securing fastener. The clamping ring is mounted in the body and has multiple grooves and multiple tabs. The securing fastener is mounted around the clamping ring to press the tabs of the clamping ring. The at least one sealing ring is elastic and waterproof and is mounted between separate parts on the body to prevent water from permeating the chamber of the body.

1. A waterproof cable connector comprising:
 a body having
 two outer ends and each outer end having a thread; 
 a chamber being defined in the body; 
 an external surface; 
 a middle; and 
 two through holes being respectively formed through the outer ends of the body and communicating with the chamber; 
 
 two plugs being respectively connected to the outer ends of the body and each plug having
 a hollow threaded bolt being attached to a corresponding outer end of the body and having
 an external surface; 
 an outer end having an outer thread formed on the external surface of the threaded bolt; and 
 an inner end corresponding to and being attached to the corresponding outer end of the body; 
 
 a clamping ring being mounted in the threaded bolt and having
 an external surface; 
 an inner end being mounted in the outer end of the threaded bolt; 
 an outer end; 
 multiple grooves being individually formed through the external surface of the clamping ring at intervals near the outer end; and 
 multiple tabs being formed on the outer end of the clamping ring between the grooves; and 
 
 a securing fastener being mounted around the outer end of the clamping ring, engaging the outer end of the threaded bolt near the front end and abutting the tabs of the clamping ring; and 
 
 two sealing rings being an elastic and waterproof material and being respectively mounted between the body and the plugs. 
 
     
     
       2. The waterproof cable connector of  claim 1 , wherein
 the body has an internal surface and a circular cross-section; and 
 the threads are formed on the internal surface of the body. 
 
     
     
       3. The waterproof cable connector as claimed in  claim 2 , wherein the body further has a gripping surface being formed around the external surface of the body and being polygonal. 
     
     
       4. The waterproof cable connector as claimed in  claim 3 , wherein the gripping surface is formed near the middle. 
     
     
       5. The waterproof cable connector as claimed in  claim 4 , wherein each threaded bolt further has a gripping surface being formed around the external surface of the threaded bolt between the inner and outer ends of the threaded bolt and being polygonal. 
     
     
       6. The waterproof cable connector of  claim 1 , wherein the threads are formed on the external surface of the body. 
     
     
       7. The waterproof cable connector as claimed in  claim 6 , wherein the body further has a gripping surface being formed around the external surface of the body and being polygonal. 
     
     
       8. The waterproof cable connector as claimed in  claim 7 , wherein the gripping surface is formed near the middle. 
     
     
       9. The waterproof cable connector as claimed in  claim 8 , wherein each threaded bolt further has a gripping surface being formed around the external surface of the threaded bolt between the inner and outer ends of the threaded bolt and being polygonal. 
     
     
       10. The waterproof cable connector as claimed in  claim 1 , wherein the body further has a gripping surface being formed around the external surface of the body and being polygonal. 
     
     
       11. The waterproof cable connector as claimed in  claim 1 , wherein each threaded bolt further has a gripping surface being formed around the external surface of the threaded bolt and being polygonal. 
     
     
       12. The waterproof cable connector as claimed in  claim 10 , wherein the body further has two gripping surfaces being respectively formed around the external surface adjacent to the outer ends of the body and being polygonal. 
     
     
       13. A waterproof cable connector comprising:
 a body being a hollow tube, being formed from two detachably connected segments and connected each other along an axial direction of the body by using a threaded protrusion formed on one connected segment and a recessed thread formed on the other connected segment sealably engaging each other and having
 two outer ends; 
 a chamber being defined in the body; 
 an external surface; 
 a middle; and 
 two through holes being respectively formed through the outer ends of the body and communicating with the chamber; 
 
 two plug being respectively connected to the outer ends of the body and each plug having
 a hollow threaded bolt being formed on a corresponding outer end of the body and having
 an external surface; 
 an inner end being formed on the body; and 
 an outer end having an outer thread formed on the external surface; 
 
 a clamping ring being mounted in the threaded bolt and having
 an external surface; 
 an inner end being mounted in the outer end of the threaded bolt; 
 an outer end; 
 multiple grooves being individually formed through the external surface of the clamping ring at intervals near the outer end; and 
 multiple tabs being formed on the outer end of the clamping ring grooves; and 
 
 
 a securing fastener being mounted around the outer end of the clamping ring engages the threaded outer end of the threaded bolt and abuts the tabs of the clamping ring; and 
 a sealing ring being an elastic and waterproof material and mounted between the two segments of the body. 
 
     
     
       14. The waterproof cable connector of  claim 13 , wherein the body further has two gripping surfaces being respectively formed around the external surface adjacent to the outer ends of the body and being polygonal.
